Commonwealth of the U.S. and between the Caribbean Sea and the North Atlantic Ocean (east of the Dominican Republic) you will find the island of Puerto Rico. Puerto Rico is considered to have one of the most dynamic economies in the Caribbean. Therefore, you will notice that the island is very well maintained. It has a rich history (especially in Old San Juan), tropical climate, diverse natural scenery, but also shopping malls and casinos. Puerto Rico has a beautiful rainforest; El Yunque, and what’s truly unique is their magical bioluminescent bay (bio bay). It is water that contains millions of micro-organisms, called “dinoflagellates”, which glow in the dark for a second when agitated. The beaches are perfect for surfers, snorkelers or people who simply want to relax. “Spanglish” was invented here and it has that Mediterranean feel in the Caribbean because of the Spanish colonial architecture.
